Abstract

See full text

A clamp system includes a frame, a plurality of clamp members, an actuator collar, and an actuator system. The frame includes an attachment member and a stop ring defining a stop cam surface. The clamp members each define first and second cam surfaces. The actuator collar defines an actuator cam surface. The actuator system displaces the actuator collar. The frame supports the actuator collar and the plurality of clamp members such that the first cam surfaces engage the actuator cam surface and the second cam surfaces engage the stop cam surface. Operation of the actuator system displaces the actuator collar towards the stop ring. As the actuator collar moves towards the stop ring, the actuator cam surface acts on the first cam surfaces and the stop cam surface acts on the second cam surfaces such that the clamp members place the clamp system in an engaged configuration.
